and hurry up , before they damage permanently your tweeters and midrange diaphragms or woofers --old caps are the worst thing for the voice coils of the woofer-mids-tweeter -
on August 27th , USA deaths were 180 000, on September 2nd , it's closer to 190 000 deaths in 6 days -we are sending our kids back to school and our own kids are magnets to viruses of all kind -the teaching staff will be on the front lines

both the KP 3.0B and the KP 3.6A are hard to find on the used side , either crossover should work fine , as long as the bad capacitors are replaced , however the KP 3.06A is a more recent crossover as it came out later by a few years , so a newer concept -
then the answer is simple , you have a pair of 2 different speakers 1) KP 301 which uses the 3,0B , and the second speaker a KP 301 II that uses the KP 3.6A - or someone swapped the wrong crossover into 1 of the speakers , if both look identical
-
it depends whether you have a KP 301 or a KP 301 II , the KP 301 uses the KP3.0B ---------here is what they should look like ----the KP 301II uses the KP 3.6A XO -
-first thing to do , is remove the 2 woofers - 2 mids--2 tweeters and verify which crossovers you have inside the speakers , and verify if both mids drivers or horns are the same and finally are the tweeters identical -
-there has been aftermarket and original diaphragms for both the mids and tweeters in both phenolic and titanium ---you would have to open each driver to see what is installed in the drivers - are they original klipsch ------are they aftermarket , are they phenolic-are they titanium -or are they all a mix of various types -
we've had 60 degrees or lower last week in Northern NY/Quebec , rained like a deluge , and even the geese are getting ready to head South , the winter will hit us very early this year -no doubt about it -
-----on the other hand , older klipsch speakera are definitely not junk , spare parts are readily available , and newer series speakers are 4-5 times the price , and the lean years are over, at least for the Heritage klipsch series lineup -
